API Integration
NXBIRD connects the software your business already uses — payment gateways, CRMs, accounting, messaging and third-party services — through their APIs. Data then moves between systems automatically, without manual copying.
What is API integration?
API integration connects two or more software systems through their APIs (application programming interfaces), so data such as orders, payments, contacts or messages moves between them automatically instead of being copied by hand.
What we build
- Payment gateway integration
- WhatsApp, SMS and email integration
- CRM and accounting integration
- Custom REST APIs
- Webhook automation
Who this is for
Copying data between systems wastes time and creates errors. We connect your tools securely so information updates in one place and flows to the rest.
- Startups
- Payments, messaging and third-party services connected to your product quickly and safely.
- Small businesses
- Website orders, CRM, accounting and WhatsApp connected so data isn't typed twice.
- Enterprises
- Secure APIs for partners and integrations between internal systems, with monitoring.
What's included
- Integration plan and data mapping
- Payment gateway integration
- SMS, email and WhatsApp messaging integration
- CRM and accounting integrations
- Custom APIs for partners or apps
- Error handling, retries and alerts
- Integration documentation
Features

- Logged
- Requests are recorded for troubleshooting.
- Documented
- Clear docs so the integration can be maintained.
- Official APIs
- Built on each provider's documented, supported APIs.
Our process for api integration
Mapping
We list the systems and the data that should flow between them.
Design
We design the data flow, error handling and security.
Build
We build the integration using each provider's official API.
Testing
We test with sandbox accounts, then with real data in a controlled way.
Monitoring & support
We monitor the integration and update it when providers change their APIs.
Technologies we use
- REST APIs
- Webhooks
- Node.js
- TypeScript

People also ask about api integration
How much does an API integration cost?
Cost depends on scope. Share your requirements and we'll send a written quote. The price depends on the features, integrations, design work and content involved. We explain each part of the quote in plain language before any work begins, so you know exactly what you are paying for.
How long does an API integration take?
Timelines depend on scope. Share your requirements for a written quote, which includes an estimated schedule with clear milestones. The schedule also depends on how quickly content, access and feedback are available. Larger projects are delivered in stages, so you can review progress before the next stage begins.
What is your process?
We follow four stages: Discover, Design, Build, and Launch & Support. First we understand your goals and agree on scope and cost in writing. Then we plan and design, build in stages with regular updates, test the work and launch it with you. NXBIRD's directors are involved from the first call to launch.
Do you provide support and maintenance after launch?
Yes. After delivery there is a 7-day testing and acceptance period, and bugs or errors you report during it are fixed free of charge. After acceptance, new features or changes are quoted separately, and ongoing support and maintenance are available through an optional annual maintenance contract (AMC).
Who owns the code and designs?
It depends on the plan in your quote. On a managed plan, hosted on NXBIRD's servers, you get your content and admin panel while we manage the server and code. On a full handover plan, source code, design and logins are handed over after final payment. Your content, logo and data always remain yours.
How do you keep the project secure?
Security is planned from the start. We use HTTPS, validate inputs on the server, keep secret keys out of the code, give each user only the access they need and keep software dependencies updated. Personal data is collected only where it is needed and handled with care.
What technology do you use for API integration?
We build integrations with Node.js and TypeScript using REST APIs and webhooks, following each provider's official documentation. Credentials are stored securely outside the code, requests are logged for troubleshooting, and errors are handled so one failing service does not break the rest of your system.
Which services can you integrate with?
We can integrate with most services that offer a documented API, including payment gateways, SMS and email providers, the WhatsApp Business Platform, CRMs, accounting software, shipping services and government service APIs. We first check the provider's documentation and access requirements, then confirm what is possible in the written quote.
